A hole 3! is provided in the base 4 at the edge of the fixed jaw adjacent the recess i i and in alignment with the partly-cylindrical recess 2! in the fixed jaw, which hole is for the purpose of receiving the shank of a resilient chuck, presently to be described.

The socket is formed in the same manner as the socket 26, as described above.

Two holes or wells 32 and 33 are provided in the fixed abutment l3 extending downwardly from the top surface of this abutment, which holes are provided to receive the shanks of extra chucks, so that several chucks of relatively different sizes can be conveniently supported on the vise at the same time, and a selected chuck can be quickly inserted into one of the sockets 25 or 26 for operation of the vise.

The chucks are all of substantially identical size and construction, differing only in the formation of their work-engaging portions, so that they will conveniently hold the work pieces of different sizes, and it is, therefore, considered suiiicient to describe, in detail, only one chuck, such as that generally indicated at 35.

The chuck comprises a cylindrical portion 36, and a cylindrical stem or shank 3! projecting outwardly from one end of the cylindrical portion 36 substantially concentric with the letter. The cylindrical portion 36 is symmetrically divided by a transversely-extending notch 36 which extends from the end of the shank 3? adjacent the cylindrical portion 36 to the opposite end of the cylindrical portion and uniformly increases in width in a direction away from the shank 37. A pair of opposed jaws 39 and 46 extends outwardly from the end of the cylindrical portion 36 opposite the shank 31, and are disposed at respectively opposite sides of the slot 38.

The jaws have a width less than the diameter of the cylindrical portion 36, are symmetrically disposed relative to the center of the symmetrical portion and have their outer sides beveled, or inclined so that they terminate in narrow outer ends. Each of these jaws has, at its outer end, a lip, as indicated at M and 42 respectively, directed toward the opposite jaw to engage a work piece, such as a watch balance wheel assembly.

Adjacent the lips 4i and 42 the slot 33 is enlarged to provide a substantially cylindrical recess 48 extending transversely between the jaws immediately under the lips and the mutually adjacent edges of the lips are semi-circularly recessed to provide two complementary halves 49 and 50 of a substantially circular opening between the jaws. A notch is provided in the end of each jaw, as indicated at 5! and 52, which notches provide clearance for the roller jewel when the roller table is seated on the jaws so that the jewel will not be damaged in the process of removing the balance wheel stair from the roller table.

The cylindrical portion 36 of the chuck is of substantially the same diameter as the sockets 25 and 26 provided by the complementary, partlycylindrical recesses, such as 21 and 28, provided in the fixed and movable jaws I2 and I5, respectively.

In using the device, a chuck is placed in one of the sockets 25 or 26 with the notch 38 in the chuck substantially in alignment with the gap between the fixed and movable jaws of the device, and with the chuck jaws 39 and 40 positioned above the fixed and movable jaws i2 and (5. A. watch balancewheel assembly, generally indicated at 43 in Figure 4, is then placed on the chuck jaws in a manner such that the chuck jaws project through spaces between the arms or spokes and the rim of the balance wheel 44, the roller table 45 of the balance wheel assembly rests upon the top surfaces of the chuck jaws, and the roller jewel overlies the notches in the ends of the jaws. The screw shaft i8 is then manually rotated to move the movable vice jaw 45 toward the fixed vice jaw i2 compressing the chuck 35 and forcing the chuck jaws 39 and 46 toward each other to firmly grip the hub 46 of the balance staff 47 with the balance wheel staff 41 projecting downwardly between the chuck jaws, the balance wheel assembly being firmly held on the chuck jaws by the left hand of the watchmaker while the watchmaker rotates the screw shaft with his right hand by means of the knurled head 24 on the screw shaft.

After the balance wheel assembly 43 has been clamped in the chuck jaws, a punch of the proper size is set on the upper end of the balance wheel staff 4'! and positioned substantially vertically and in axial alignment with the balance wheel stair. The upper end of the punch is then given a sharp blow with a small hammer to drive the staff out of the roller table 45. After the staff has been removed from the roller table, the screw shaft 18 is rotated in a direction to move the movable vice jaw i5 away from the fixed vice jaw l2 permitting the chuck 35 to expand, whereupon the disassembled balance wheel assembly can be easily removed from the chuck.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristic-s thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:
